C++ -> CSharp usage of std_map.i ?

[kentavr]

Hi All,

I am new to swig and here is the question:

I am looking for example how I can use specialized templates defined in std_map.i.
It looks like that template specialize_std_map_on_both can solve my problem. (may be not)
My function in C++ returns std::map<std::string,double> foo();
declared in my.i file as

%include "C:\swig\swigwin-1.3.39\swigwin-1.3.39\Lib\csharp\std_map.i"
%template(DoubleMap) std::map<std::string,double>;

When I am trying to access values in this map from C# the return type is not "double".
I had to do this:
 SWIGTYPE_p_double swD = myMap.get(s);
I bet that there should be an easy way to export pure doubles.

Thanks for any help,
Sergey

std::map was radically overhauled for C# in 1.3.40. Please try this
updated version.

Thanks a lot for the advice.
Map in 1.3.40 works like a charm.
